InMemoryCloudDatastoreStub 0.0.15

An in-memory stub implementation of Google Cloud Datastore for use in unit tests

An In-Memory Stub for Google Cloud Datastore

This project is a pure python implementation of the Google Cloud Datastore RPC Spec. This allows projects using the python-ndb lirary to write unit tests without needing to depend on/manage the full datastore emulator.

Installing

InMemoryCloudDatatoreStub can be installed from PyPi:

$ pip install InMemoryCloudDatastoreStub

Using

The stub can be inserted into your unit tests as a pytest fixture using monkeypatch:

from unittest.mock import magicMock

import pytest
from InMemoryCloudDatastoreStub.datastore_stub import LocalDatastoreStub

@pytest.fixture()
def ndb_stub(monkeypatch):
    stub = LocalDatastoreStub()
    monkeypatch.setattr(_datastore_api, "stub", MagicMock(return_value=stub))
    return stub
